Verification infrastructure for AI coding agents

LoopGate makes agents prove the code works.

Run Claude, Codex, Copilot, or any prompt-reading CLI agent with repo-specific tests, lint, type checks, and security scans. Set the plan and quality gates, then require each iteration to pass.

AI agents ship faster than teams can trust.

Coding agents can generate useful changes, but teams still need a repeatable way to decide whether the work should be accepted. LoopGate turns that acceptance step into an explicit verification loop.

Agent sprawl

Every tool speaks a different dialect.

Claude, Codex, Copilot, Cursor, and custom agents all need the same bar for evidence before their work lands.

Weak acceptance

Vibes are not a merge policy.

Teams need repeatable checks before a commit or push. Run fast preflight checks often and the full gate before pushing.

Real repos

The gate has to fit the codebase.

LoopGate is designed around repo-local commands and context instead of generic demos that collapse on contact with production code.

A harness for verified agent work.

Each fresh agent iteration reads the plan and specs, makes a bounded change, updates progress, and commits through quality gates. Failed checks must be repaired before a blocking gate allows work through.

Collect context

Load the repo, target files, task intent, and acceptance criteria.

Run the agent

Let the selected coding agent produce a bounded change.

Verify locally

Run tests, lint, type checks, security scans, and custom gates.

Save progress

Update specs and status, then commit through the repo checks.

What AI slop?

Agents can edit. Your quality standards decide what lands. Watch the 60-second introduction to LoopGate.

An illustrative workflow: the agent reads your plan and specs, faces automatic commit and pre-push checks, and must repair failures to continue. Mutation testing tests the tests. Forbidden files, patterns, and diff limits contain the work. Markdown and code carry progress across fresh contexts. Works with CLI loops and interactive agent sessions. Music only; all demo text is shown on screen.
Run any CLI agent in a loop, or apply the same repo standards to interactive Claude and Codex sessions.
Require each iteration to pass repo-local quality gates.
Keep specs, status, logs, and commits available to the next iteration.

Fast code is not the milestone. Verified code is.
